Title: Process for the manufacture of chloracetic cellulose esters
IPC: C08B3/14
Filed: 1928-06-12
Abstract: 318,908. Soc. des Usines Chimiques Rh¶ne-Poulenc, (formerly Soc. Chimique des Usines du Rhone). Gault, H., and Bidaud, F. June 12, 1928. Right to Patent relinquished. Cellulose carboxylates. - Cellulose esters of monochloracotic acid are prepared by heating cellulose or its near conversion products, such as oxyeellulose or hydrocellulose, with monochloracetic anhydride in the presence of a catalyst such as sulphuric acid, methane sulphonic acid, or zinc chloride. Cellulose chloracetate can be separated from the more or less viscous solutions obtained by precipitation with ether or alternatively a product containing a lower percentage of fixed chlorine and less soluble in organic solvents can be obtained by diluting the reacting mass with ether before the cellulosic fibre has dissolved. The esterification may be effected in presence of a diluent, for example, monochloracetic acid. In one example, cotton or wood pulp is heated at 55-60‹ C. with monochloracetic anhydride. A melted mixture of monochloracetic anhydride and sulphuric acid is then added and after the mass has disintegrated, the mixture is further heated at 60‹ C. to give a viscous solution from which cellulose monochloracetate containing 22.5 per cent of chlorine is precipitated. for example by ether or alcohol. By evaporation of the ether or alcohol, the excess of these reagents can be recovered. In another example, the procedure is the same except that zinc chloride is employed as catalyst and the heating is conducted at 80‹. Transparent films can be obtained by evaporation of solutions of cellulose monochloracetate.

Title: Improvements in clutch-controlled driving mechanism
IPC: F16H15/12
Filed: 1920-06-24
Abstract: 173,533. Bergey, A. E. June 24, 1920. Steam and other power cultivation of land.- In driving-mechanism, particularly applicable to winding-apparartus for hauling agricultural implements, such as rakes, a friction clutch is held in engagement, against spring-pressure, by camsurfaces on a controlling-member, normally prevented from backward rotation to release the clutch by its connection to the driving shaft through a friction coupling which, however, can be caused to slip by means operable from a distance. A shaft 6, Fig. 1, driven by a motor 5, has secured to it one member 7 of the friction clutch and one member 18 of the friction coupling. The other clutch-element 8, loose on the shaft 6 and pressed by a spring 16, is carried by'a drum 4, on which is wound a rope 3 connected to the rake &c. 1. A boss 13 of the drum 4 is provided with cam-surfaces, shown developed in Fig. 2, coacting through rollers 11 with cam-surfaces on a boss 14 of the controlling-drum 9, which is of the same diameter as the drum 4. The camsurfaces may terminate in projections 15 to prevent excessive relative rotation of the parts 4, 9. The drum 9 is provided with a controlling-cord 10 operable, to the extent of a slot 21, by a slide 20 on the handle 2 of the rake &c., and has secured to it, through an adjustable blade spring 17, the second member 19 of the friction coupling. The friction of the coupling 18, 19 derived from the end-thrust of the cams is just sufficient t) prevent the drum 9 from turning backwards under the torque of the cams, but the coupling may be caused to slip and the clutch 7, 8 disengaged by a pull on the cord 10, release of which permits rotation of the parts 19, 9, effecting reengagement of the clutch. For heavy drives, where the end-thrust is considerable, the operating-pull may be kept small by a multiplication of the arrangement in series; for instance, as shown in Fig. 6, by a duplication. The main clutchmembers 7a, 8a transmit their full end-thrust through cam-surfaces and rollers or, as shown, balls 11<1>, to an intermediate controlling-member 9<1> and coupling disc 18<1> secured to the driving- shaft. The torque of the cams normally overcomes the coupling 18<1>, 19<1>, but is itself overcome by the additional torque transmitted through a sliding-claw coupling 22 from an auxiliary clutch 7<1>. 8', held in engagement by cams, rollers 11, and the primary slipping-coupling 18<a>, 19<a>. When the rotation of the controlling drum 9<a> is stopped by the cord, the clutch 7', 8<1> disengages the coupling 18<1>, 19<1> slips, and the main clutch 7<a>, 8<a> is thrown out.

Title: Improvements in and relating to radio communication systems for the navigation of aircraft
IPC: G01S1/02
Filed: 1941-06-05
Abstract: 557,903. Automatic control systems. HUGHES & SON, Ltd., H., SPROULE, D. O., and HUGHES, A. J. June 5, 1941, No. 17407/42. Divided out of 557,870. [Class 38 (iv)] [Also in Group XL] A radio navigation system for aircraft comprises means on the ground for radiating in succession four spaced beams which overlap to define a flight path, and means on the aircraft whereby its position may be found by determining the intensity and phase of the received signals. Two or more of the four beams A, B, C, D, radiated in succession, are given different modulation frequencies, beams A, C defining the flight path in a vertical plane (left right) and beams B, D in a horizontal plane (up down). When the aircraft is following the defined path, all four beams are received in equal strength, but when it deviates from the vertical plane, say, the signals from beams A, C are unequal in amplitude, and are caused to produce an alternating current whose amplitude depends upon the difference in amplitude of the received signals and whose phase depends upon which is greater, Figs. 4 to 14 (not shown). This alternating current is measured with the aid of a reference phase derived from the beams B, D, the signals from which are passed through limiters (so as to produce pulses of equal intensity even if the signals received from B and D are unequal) and caused to produce an alternating current of fixed phase and amplitude. Similarly, if the aircraft deviates from the horizontal plane, the signals from beams B, D are unequal in amplitude and produce an altenating current of phase and amplitude determined by the direction and amount of deviation this current being measured with the aid of a reference current of fixed phase derived from the beams A.C. Fig. 2 shows the apparatus on the ground for producing the four spaced beams, comprising what may be regarded as a localizing transmitter A1 and a glide path transmitter A2, each having two radiating positions. Transmitter A1 is at one end of the approach path R and is oscillated to radiate in the directions B1, D1 on each side of the path R, a switch 27 connecting up modulating frequencies N1, N3 in the two extreme positions, so that the beams are modulated respectively at these two frequencies, which may be 1000 and 3000. The glide path transmitter A2 is at one side of the approach path, and oscillates in a vertical plane, radiating in two directions beams modulated at 2000 and 4000. The two transmitters are synchronized so that the four signals of frequencies 1000, 2000, 3000, 4000 are received in regular sequence being used as described above. In a modified system, only two modulation frequencies are used. Figs. 18 to 26 (not shown). The signals may be led to centre zero dynamometer indicators, or may control two phase motors for automatic steering of the aircraft.
